Core Insights - The article discusses the successful deployment of a stratospheric balloon, "Jimu No. 1," developed by the Chinese Academy of Sciences for atmospheric observation in the Tibetan Plateau [1][2]. Group 1: Development and Technology - "Jimu No. 1" is a tethered balloon that utilizes helium for lift and is designed to function as an aerial mobile laboratory, equipped with 16 scientific instruments weighing approximately 200 kilograms [2]. - The development of "Jimu No. 1" involved eight years of research, overcoming challenges such as slow inflation rates and high leakage, leading to significant improvements in durability and reusability [2]. - Over the past five years, more than 60 patents related to the stratospheric balloon have been filed, enhancing technological independence and innovation in the field [2]. Group 2: Scientific Research and Applications - The Tibetan Plateau, known as the "Asian Water Tower," is crucial for the water supply of major rivers and supports the livelihoods of 2 billion people [3]. - The balloon's mission aims to quantify the spatiotemporal distribution of water vapor and its sources, contributing to understanding the dynamics of the "Asian Water Tower" [3]. - "Jimu No. 1" has successfully conducted atmospheric observations at altitudes up to 5,900 meters, capturing critical data on atmospheric components and pollutants [3]. Group 3: Future Prospects and Collaboration - The stratospheric balloon is positioned as an open platform for scientific research, inviting other scientific instruments to utilize its capabilities for various studies [5]. - The team has planned new tasks for "Jimu No. 1," including monitoring grassland conditions and addressing communication challenges in remote ocean areas [5].
